The feature tracks the changes of all modifying operations executed via CQN statements, which are indirectly triggered
by the protocol adapters or directly by a custom code.
Changes made through the native SQL, JDBC, or other means that bypass the CAP Java runtime or that are forwarded
to the remote services aren't tracked.
This page covers **`cds-feature-change-tracking`**, a Java runtime library that intercepts modifying CQN operations to record changes. If you are evaluating options, there is also the [**`@cap-js/change-tracking` v2 plugin**](../plugins/#change-tracking), which captures changes via database triggers and works for both Node.js and Java — see the [project repository](http://github.com/cap-js/change-tracking) for its documentation.

| | `cds-feature-change-tracking` | `@cap-js/change-tracking` v2 |
|---|---|---|
| **Mechanism** | CAP Java runtime (CQN layer) | Database triggers (generated at build time) |
| **Java support** | Yes | Yes |
| **Node.js support** | No | Yes |
| **Captures non-runtime writes** | No | Yes |
| **Extensible via event handlers** | Yes (`createChanges` event) | No |
